Engine Air Intake Hose Replacement

The engine air intake hose forms part of the connection between air filtration components and the engine intake system. Correct hose shape, connection diameter and clamp positioning are important for maintaining a sealed air passage during excavator operation.

An intake hose showing cracking, deformation, damaged connections or air leakage should be inspected and replaced when necessary. During replacement, compare the hose routing and both connection ends with the original component to avoid incorrect fitment.
